2 Claims.

This invention relates to improvements in binding devices for books,magazines, pamphlets and the like, having for an object to provide adevice engageable with the leaves or sheets of such an article wherebythe same will be permanently retained in assembled bound relation.

It is also an object of the invention to provide a binding device ofsuch formation as to be readily engageable with the leaves or sheets ofan article to be bound thereby without detrimentally affecting theutility, services or other physical characteristics of such leaves orsheets.

Moreover, it is an object of the invention to provide a device of thestated character, which, when operatively engaged with the leaves orsheets of a book, etc., will, in addition to serving as a bindertherefor, afford additional body or stiffening to such articles, and anovel form of insert leaf.

Other objects of the invention will be in part obvious and in partpointed out hereinafter.

In order that the invention and its mode of operation may be readilyunderstood by those skilled in the art to which it appertains, I have inthe accompanying drawing and the detailed description based thereupon,set out two embodiments of my invention.

In the drawing:

Figure 1 is a side elevation of a book, magazine, pamphlet or the like,constituted in accordance with my invention.

Figure 2 is an end elevation of the same.

Figure 3 is a detail in side elevation of the improved binding device.

Figure 4 is a fragmentary elevation of a folded sheet constructed in amanner for usage in the practicing of my invention.

Figure 5 is a side elevation of a slightly modified form of theinvention, wherein a greater number of foldable binding fingers areutilized.

Figure 6 is a fragmentary elevation of that particular type oflongitudinally folded sheet adapted for use in connection with the formof invention illustrated in Figure 5; and

Figure 7 is a fragmentary elevation of a modifled form of binding devicefor usage in connection With the form of invention disclosed in Figures5 and 6.

Having more particular reference to the drawtrated and consists of aplurality of relatively 55 sheet juxtaposed or assembled longitudinallyfolded sheets of paper or other suitable or similar material, generallydesignated by the reference character I, said sheets, as illustrated inFigure 4, being preferably longitudinally folded along the dotted lineindicated at 2. Each of the sheets i is'formed with relatively spacedlongitudinally disposed slits 3 and 3' extending along their respectivelongitudinal folds 2, and it will be noted, in this connection, that theslits 3 and 3 of each said sheets are adapted to be brought intoregistering relationship with'juxtapositioning or assembling of saidsheets in the manner shown in Figure 2. j

' With a view toward providing thejuxtaposed or assembled sheets I with.effectual means whereby they will be bound or locked in their thuscollated formation, I provide a sheet-like body or element 4, preferablyconstructed or made from material having greater body or more rigiditythan that possessed by said sheets I. Flexible, foldable fingersiiand 5'are provided adjacent one longitudinal side or edge of the body 4. Ifdesired, these fingers may be formed integral with thebody 4, insolongas their arrangement or positioning upon such body is substantially thatas illustrated in Figure 3 of the accompanying drawing. Said fingers 5and. 5' are so relatively spaced as to coincide With the spacingbetweenthe slits 3 and 3' in the longitudinally folded sheets I;moreover, they are formed in lengths quite sufficient to permit theirpassage through and the extension of material portions thereof beyondthe outermost of said sheets I, as indicated in Figures 1 and 2 of thedrawing. Thus, to bind the assembled longitudinally folded sheets I, thebody or element 4 is right angularly positioned adjacent thelongitudinal fold of the innermost of said sheets I; these fingers 5 and5' are aligned with the relatively spaced slits 3 and 3' in said sheetsI whereupon the body or element 4 is thrust or moved in a direction tocause entrance of the fingers 5 and 5 into and their passage throughtheir respective or adjacent slits 3 and 3' in the longitudinally foldedsheets I. With such positioning of the body 4 and the engagement of itsfingers 5 and 5' through said slits 3 and 3 of the sheets I, the outeror extended portions of the fingers 5 and 5' are then longitudinallyflexed or folded in a manner to bring said fingers into flush orsubstantially flat contacting relationship to adjacent portions of theouter side of the outermost I, as is clearly illustrated in Figure 2,

whereupon an adhesive may be applied to the inner sides or faces of saidextended portions of the fingers and 5' whereby they may be fastened oradhered thereto and thus be prevented from becoming displaced orpermitting the body of the binding device or element from becomingdislodged or displaced with respect to the thus interconnected or boundlongitudinally folded sheets 1.

Whereas it have described with some degree of particularity, the fingers5 and 5 as being joined by an adhesive to adjacent portions of the outermost sheets I, it of course will be understood and appreciated thatvarious other forms of connecting or securing means or methods may beutilized, such as are Well known in the art.

In Figures 5, 6 and '7, I have illustrated a somewhat modified form ofmy invention. In this particular form of the invention, a greater numberof flexible or foldable binding fingers, such as indicated by thenumerals 5 .and 5' in the fingers l,-2 and 3, areutilized, Abindingdevice or element body 4*, substantially corresponding to that describedin the preceding embodiment of my invention, is employed. This body 4 isprovided adjacent one of its longitudinal edges or sides with. aplurality of later-ally and outwardly extending flexible orfoldablebinding fingers 5 which fingers may be joined to said body l ormay be integral therewith. Each of said binding fingers .5 is preferablytransversely scored or weakened, as. indicated at 6, whereby to betterfacilitate their transverse folding or flexing for that purposeheretofore described and to be hereinafter additionally-described. Thetype of sheets 2',

to be bound inbook, magazine, pamphlet or similar form, herein describedby the numeral 1', are each longitudinally folded, as indicated at 8.Each of said sheets is provided complementally arranged and relativelyspaced longitudinally disposed slits or openings 9, whose respectivelengths are such as to substantially correspond tothe Widths of eachsaid binding fingers 5 Sheets to be bound according to this particularmodified form of my invention are folded along their respective foldlines '8. They are thus arranged in substantially juxtaposed orassembled relationship. Thereupon, the binding fingers 5 carried uponthe body 4 of the binding device are passed outwardly through" therelatively registering and spaced slits 9 so as to bring the adjacentlongitudinal edge or side of said body 4 into abutting or adjacentrelationship to the intermediate portions of the innermost of saidsheets i. At this time, the binding fingers 5 are flexed or folded alongtheir weakened or scored portion 6 and are then joined by an adhesive orother securing means to adjacent portions of the outermost of saidassembled sheets 1, in the same fashion as are the binding fingers 5 and5' of the body 4 of the binding device disclosed in Figure 3, broughtinto engagement with the outermost sheet I disclosed in Figure 2. Whenso engaged, the thus interconnected sheets will be securely and durablyretained in bound booklet, magazine, pamphlet or like formation orrelations-hip.

Manifestly, the construction shown is capable of still furthermodification, and such modification as iswithin the scope of my claims,I consider within the spirit of my invention.

I claim:

1. In combination, a plurality of relatively nested longitudinallyfolded sheets, each having spaced and registering openings formedtherein adjacent to their longitudinal folds, a sheet-like andcomparatively stiffer body arranged adjacent and along the fold oftheinnermost of said nested sheets, and flexible fingers carried by andextendin beyond one sideof said sheet-like body engaging through theregistering openings in said folded sheets and having their extendedfree portions flexed into binding and clamping engagement with respectto the outermost of said folded sheets and their remaining portionsfixedly connected to adjacent portions of the outer side of one portionof said outermost folded sheet.

2. In combination, a plurality of relatively nested longitudinallyfolded sheets, each having spaced and registering substantiallyrectangularly shaped openings formed therein adjacent to and parallelwith their longitudinal folds, a sheet-like and comparatively stifferbody arranged adjacent and along the fold of the innermost of saidnested sheets, and flexible fingers carried by and extending beyond oneside of said sheet-like body snugly engaging through the registeringopenings in said folded sheets and hav ing their extended outer portionsbent into binding and clamping engagement with the outermost of saidfolded sheets and their remaining portions fixedly connected to adjacentportions of the outer side of one portion of said outermost sheet.
